Re: [Discuss-gnuradio] Ettus E310 sample rate

[Nick Foster]

8MS/s is about what you can stream through the host processor on E310. Full-rate streaming is supported just fine through the FPGA fabric. If you need to do faster rate streaming on the E310, you need to do the processing in the FPGA.

Happy Friday,

 

What is the max sample rate for the Ettus e310?

 

When I ssh in and perform the benchmark_test, I get the following:

 

$/usr/lib/uhd/examples/benchmark_rate --rx_rate 12e6 --tx_rate 12e6

.

 . [other stuff here]

   .

UHD Warning:

    The hardware does not support the requested TX sample rate:

    Target sample rate: 12.000000 MSps

    Actual sample rate: 8.000000 MSps

Testing transmit rate 8.000000 Msps on 1 channels

 

When I set the target sample rate to 16MS/s, I get OOOOOOOOOO.

 

Does this mean that 8MS/s is the highest sample rate which the e310 will work?

 

The data sheet says the max ADC/DAC sample rate is 61.44MS/s, so shouldn’t I be able to stream data at a divisible of this?
